Biochar led induced resistance to control Fusarium oxysporum f.sp. lycopersici

Abstract

Bio-char, a highly carbonaceous organic byproduct of pyrolyzed organic wastes which have shown a great significance in agriculture. It has been used in inducing resistance in plants by stimulating the activity of PR-proteins and phenolic compounds, stimulates the physical characteristics and chemical compositions of soils helping to prevent the numerous soil borne pathogen. It has been used against Fusarium oxysporum f.sp. lycopersici (FOL). Biochar is added in soil as an amendment with different concentrations (ranging 0.5%-5% w/w) to induce resistance into tomato plants. It has been seen that Biochar induces the resistance with increase in the level of total phenols by 64.44% and soluble proteins upto 91.51% over control at 3% conc. Biochar has increased the phenols content upto 2.22 mgCE/gFW and proteins content upto 27.98 mgBSA/gFW at 3% conc. Under in vitro analysis biochar inhibits the mycelium percentage by 15.62% at 3% concentration.
